How it works

Finds every device

Scans your Wi-Fi automatically every few seconds — no manual device list to maintain.

Becomes the middleman

ARP-spoofs each device so its traffic routes through your machine, then rate-limits it in the kernel (or the OS-equivalent).

You choose who's exempt

Pick yourself, your partner, anyone — by MAC address, saved across restarts. Everyone else stays throttled by default.

OS	ARP spoofing	Traffic shaping
Linux	arpspoof (dsniff)	tc (HTB)
macOS	arpspoof (dsniff)	pfctl + dnctl
Windows	pnet + Npcap	WinDivert
